IMPROVEMENT IN PRUNlNG-IMPLEMENTS.

Specification forming part of Letters Patent No. 155,100, datedSeptember 15, 1874; application filed September 1, 1874.

To all whom it may concern Be it known that I, WILLIAM MILLSPAUGH, ofMiddletown, in the county of Orange and State of New York, have inventedcertain new and useful Improvements in Pruning-Tools; and I do herebydeclare that the following is a full, clear. and exact descriptionthereof, which will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My lHVBIltlOll relates to that class of pruning-tools in which a saw anda knife are combined in one instrument; and the nature of my inventionconsists in the frame, with arms for the saw, provided with sockets forthe handle, which extends the entire length of the saw, and one of thesockets with a set-screw, as will be hereinafter more fully set forth.

The accompanying drawing represents a side view of my improvedpruning-tool.

A represents the ordinary saw-blade used in this class of pruning-tools,which blade is attached at its ends to a frame, B. At the inner end ofthe frame B is formed a short tube or ferrule, G, and at the outer endis formed a socket, D. E is the usual round handle, which is passedthrough the tube or ferrule G, extends the entire length of the frameand saw, and the end thereof is inserted in the socket D. The handle isthen fastened by means of a set-screw, a, passed at an angle through thesocket 0, near its outer end. This set-screw. being at an angle, has atendency to crowd the handle into the socket D, and hold it there,making it perfectly secure.

Ordinarily the handles in this class of tools have been inserted in ashort socket at the inner or lower end of the instrument, and would,therefore, often come loose.

By my method of extending the handle the entire length, the instrumentis rendered much stronger and durable, and allows of the instrumentbeing handled with greater ease; and by my method of fastening thehandle, it is impossible for it to come out until the set-screw a isunscrewed.

At the outer end of the frame B is inserted and fastened the knife G.This knife has a V-shaped slot or opening, but the sides thereof are notmade straight. These sides or cutting-edges b b are made convex, asshown in the drawing, which is of great advantage.

When using the knives having straight outting-edges, the limb will oftenslip down to the angle of the knife before it commences to cut and itsometimes also happens that, when one half of the limb is cut through,the knife will slip and out with the grain of the wood.

By making the cutting-edges convex, the knife will commence to cut assoon as it is pushed against the limb, no matter what part of the edgecomes in contact with the limb, and the limb or branch will be cut offclean, without any splitting.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The frame B, with arms for the saw, and provided with sockets (J D ateach end, in combination with the handle E, extending the entire lengthof the saw, and the set-screw a, as and for the purpose specified.

2. The device herein described, consisting of the saw A, frame B,sockets O D, extended handle E, knife G, and set-screw a, substantiallyas and for the purpose specified.

In testimony that I claim the foregoin g as my own I affix my signaturein presence of two witnesses.

WM. MILLSPAUGH.
